It’s text on a screen, so forgive me for not picking up what you’re laying down. Spoon feed it to me please. Not sure if I’ve seen women use the term, but definitely black dudes.
I get the spirit of what you're saying but strictly speaking when Blacks refer to Whites as "whitey", they're referring to all of us, not just the men. But they tend to focus on men because throughout history, white men occupied positions of authority and power - whether as prison guards, politicians, school principals, lawyers, cops, etc. Women were peripheral in the sense that they were attached to those men, but didn't execute their functions or hold their positions in society.
What's funny is that white women are now their own worst enemy in relation to their hatemongering and identity-politics/race baiting toward all whites, particularly those of the masculine persuasion and the women who support them. But in reality they're only making a laughing stock of themselves because in the eyes of a Black or Brown or Asian man, a white person is a white person, even if it's a pseudo-populist, preachy, guilt-ridden white girls from the suburbs with dreadlocks and a #meToo patch stitched to her backpack at anti-Trump rallies.
